JOSEPH-WILFRID DUMONT, 01? KATAHDIN IRON WORKS, MAINE FUNNEL.

Application filed December 28, 1822.

To all whom it may concern:

Be it known that I, JOSEPH-Human DU- MONT, a subject of the King ofGreat Britain, residing at Katahdin Iron ll'orks, in the county ofPiscataqnis and State of Maine, have invented new and useful lnrprovements in Funnels. of which the following is a specification.

This invention relates to funnels for use in filling receptacles of anykind with any liquid, and has for its object. the provision of a novelfunnel which is equipped with means for closing the outlet end thereofwhen the receptacle is full and also for closing this end while thefunnel containin the liquid is being transported from the fil ingstation to the receptacle to he filled, as occurs in many instances.

An important object is the provision of a funnel of this character inwhich the menr her for closing the outlet end is formed with airpassages communicating with an air tube which will permit the air withinthe rec-eptacle to escape as the liquid is poured in, this featureheingof "teat advantage in saving time during the filling operation.

An additional object is the provision of a funnel of this characterwhich will be simple and inexpensive in manufacture, highly elficicnt inuse, durable in service and a general improvement in the art.

With the=ahove and other ohjects and advantages in view the inventionconsists in the details of construction to he hereinafter more fullydescrihcd and claimed and illustrated in the accompanyin; drawings. inwhich:

Figure 1 is a longitudinal section through the funnel showing itinserted into a recclr tacle being filled,

Figure 2 is a plan view.

Figure 3 is a iorizontal section taken at the. neck of the funnelFigure. 4 is a horizontal section taltcn through the stopper member orvnlvm The remaining figures are detail views.

Referring more particularly to the drawings the letter A designates anyreceptacle to he. filled with a liquid, and B represents the necktheicof. In carrying out my invention I provide a funnel shaped body 10of conventional design having the usual main portion 11 and reduced orneck portion 12 which is insertable within the receptacle to be filled.At one side this funnel member carries a handle 13. The material andsize Serial H0. 803,871.

of the funnel is a matter of no great cm. sequence as any desiredvariations in these details may be resorted to.

Extending transversel of the tunnel are spiders 14 and 15 suitah ymounted in place and constituting bearings for a vertically extendingair tube'lti which has its upper end coiled or curled to )lOViCle ahandledivergent relation through the material of the stopper and whichhave their free ends directed toward one another and forced intopenetrating engagement within the stop r as shown at 21 for the purposeof rigidly securing the stopper-to the tube. The stopper is also formedwith a plurality of up wardly converging: passages 22 which c0mruuniratewith the lower end of the air tube, and the stopper is also formed witha. central passage 23 conununicat-ing with the junctures of theseinclined passe in the use of the device it will be seen that by pullingup upon the handle 17, the stopper 1.? will he forced into the outletend of the funnel so as to form a seal or closure therefor so that thetunnel full of liquid may he carried from one place to another where thefilling; is to be accomplished. Assuming that the funnel is full and thesto per iS ClOsed. the operator in;'

sorts the out et end of the funnel into the re upon the handle [7. Whenthis is done the weight of the contents will unseat the stop per 18 andpermit the liquid to flow into the. receptacle. If the device is notuaed in this way it may he used in the sarnolitunmar its an ort'liuarfunnel. that is iljl's inserted into the receptacle without itl'ieingnecessary to manipulate the handle 17 or stoppcr'at all. Liquid may thenbe poured into and through the funnel in the ordinary manner and as theliquid enters the receptacle it. i apparent that the air displaced willpass out through the passages 22 and 2 3 into the tube 16 from which itwill escape into the atmosphere. This feature is of great importance aspermitting rapid filling of the receptacle. When'the receptacle becomesfull the liquid will float the stopper and lflllSt it to close theoutlet end of the funnel so that no more liquid will enter thereceptacle and cause overflowing thereof. When this occurs it isevidenced by the upward movement. of the tube 10 Jlld the operator maythen hold the handle to keep the stopper closed'and remove the -so thatthe device should have a long life and satisfactorily perform all of itsfunctions. Y

WhileI have shown and described the preferred embodiment of theinvention it is of course to be understood that I reserve the right tomake such changes in the form, construction and arrangement of parts aswill not depart frbmthe s irit of the invention or the scopet-ofg the sujoined claims.

Having thus described my invention I claim:

1. A funnel comprising a tapered body 1 terminating in a reduced spoutadapted for 'insertion within a filling opening In a receptacle tobeiafilled, guides within the body, a tube slida-blh'through said guidesand having one and formed into a. handle loop projecting aboveithe topof the shell, bot ends of the tube being open, and a buoyant stoppersecured upon the lower end of the tube beneath said spout and adapted tobe moved upwardly for closing the same when the level of liquid withinthe receptacle being tilled reaches a certain point, said stopper beingformed nearits upper end with passages leading from the outside thereofto the tube. said tube being formed with holes registering with saidpassages.

2. it funnel comprising a funnel shipped hollow body, supporting spiderstherein, an axially extending tube having one end extending above thefunnel and provided with a handle, and a buoyant stopper carried by thelower end of said tube and adapted to close the outlet end of thefunnel, said stop: per being provided with passages communicating withsaid tube for permitting the escape of air, and said tube extending tothe bottom of the stopper and having .both ends open.

3. A funnel comprising a funnel shaped hollow body. supporting spiderstherein, an axially extending tube having one end extending above thefunnel and formed into a handle, and a buoyant stopper carried by thelower end of said tube and adapted to close the outlet end of thefunnel, the lower end of said tube extending through the stopper andbeing split to define 11 series of divergent arms embracing the bottomand sides of the stopper, the free ends of said arms having penetratingengagement with the stopper. I i i In testimony whereof I affix mysignature.
